Description
-----------
The workspace data are stored in the file in columns: the first column contains the X-values, followed by pairs of Y and E values. Columns are separated by commas. The resulting file can normally be loaded into a workspace by the :ref:`algm-LoadAscii` algorithm.

The algorithm assumes that the workspace has common X values for all spectra (i.e. is not a `ragged workspace <Ragged Workspace>`__). Only the X values from the first spectrum in the workspace are saved out.
Usage
-----
**Example - Save a workspace in CSV format**
.. testcode:: ExSaveASCIISimple
#import the os path libraries for directory functions
import os
# create histogram workspace
dataX1 = [0,1,2,3,4,5,6,7,8,9] # or use dataX1=range(0,10)
dataY1 = [0,1,2,3,4,5,6,7,8] # or use dataY1=range(0,9)
dataE1 = [1,1,1,1,1,1,1,1,1] # or use dataE1=[1]*9
ws1 = CreateWorkspace(dataX1, dataY1, dataE1)
#Create an absolute path by joining the proposed filename to a directory
#os.path.expanduser("~") used in this case returns the home directory of the current user
savefile = os.path.join(os.path.expanduser("~"), "AsciiFile.txt")
# perform the algorithm
SaveAscii(InputWorkspace=ws1,Filename=savefile)
print "File Exists:", os.path.exists(savefile)
.. testcleanup:: ExSaveASCIISimple
os.remove(savefile)
Output:
.. testoutput:: ExSaveASCIISimple
File Exists: True
**Example - Save a workspace as ASCII with a different delimiter**
.. testcode:: ExSaveASCIIDelimiter
#import the os path libraries for directory functions
import os
# create histogram workspace
dataX1 = [0,1,2,3,4,5,6,7,8,9] # or use dataX1=range(0,10)
dataY1 = [0,1,2,3,4,5,6,7,8] # or use dataY1=range(0,9)
dataE1 = [1,1,1,1,1,1,1,1,1] # or use dataE1=[1]*9
ws1 = CreateWorkspace(dataX1, dataY1, dataE1)
#Create an absolute path by joining the proposed filename to a directory
#os.path.expanduser("~") used in this case returns the home directory of the current user
savefile = os.path.join(os.path.expanduser("~"), "AsciiFile.txt")
# perform the algorithm
SaveAscii(InputWorkspace=ws1,Filename=savefile,Separator="Space")
print "File Exists:", os.path.exists(savefile)
.. testcleanup:: ExSaveASCIIDelimiter
os.remove(savefile)
Output:
.. testoutput:: ExSaveASCIIDelimiter
File Exists: True
**Example - Save a workspace as ASCII with a different comment indicator**
.. testcode:: ExSaveASCIIComment
#import the os path libraries for directory functions
import os
# create histogram workspace
dataX1 = [0,1,2,3,4,5,6,7,8,9] # or use dataX1=range(0,10)
dataY1 = [0,1,2,3,4,5,6,7,8] # or use dataY1=range(0,9)
dataE1 = [1,1,1,1,1,1,1,1,1] # or use dataE1=[1]*9
ws1 = CreateWorkspace(dataX1, dataY1, dataE1)
#Create an absolute path by joining the proposed filename to a directory
#os.path.expanduser("~") used in this case returns the home directory of the current user
savefile = os.path.join(os.path.expanduser("~"), "AsciiFile.txt")
# perform the algorithm
# CommentIndicator can be changed, but when read back in must be specified
SaveAscii(InputWorkspace=ws1,Filename=savefile,CommentIndicator="!")
print "File Exists:", os.path.exists(savefile)
.. testcleanup:: ExSaveASCIIComment
os.remove(savefile)
Output:
.. testoutput:: ExSaveASCIIComment
File Exists: True
